Purpose: The aim of this research note is to introduce a new appraisal form, the Classroom Communication and Collaboration (C3) Appraisal, designed to evaluate communication and collaboration within classroom settings. Method: A comprehensive synthesis of the key skills from a broad range of publications on successful communication and collaboration in the classroom was conducted. The resulting appraisal comprises 39 items across six scales: crafting clear messages, appropriateness of communication exchange, active listening, pragmatics and discourse, communication breakdown, and collaboration. To demonstrate its application, an exemplar usage of the C3 Appraisal involving a hearing child and a child with hearing loss engaged in a collaborative learning task is presented. Results: The C3 Appraisal allowed for the quality and successfulness of the collaborative learning task between the two children to be assessed and quantified across the six scales. Conclusions: These findings highlight the utility of the C3 Appraisal as a valuable tool for evaluating communication and collaboration in classroom environments. Next steps are to test the reliability and validity of the C3 Appraisal on a large data set.
